Since the chainstays are brazed into the BB, the best fix would be to braze patches in the shape of a spears over the holes and blend them into the BB shell lug sockets. Of course that would be overkill for such a low end gaspipe frame unless you have some sentimental attachment to it. It would be a fun project you can do yourself with silver solder and a turbo propane torch.
